氮化硅升液管
氮化硅升液管采用等静压成型，气压烧结，致密性优异，在
高温条件下能够保持高机械强度。在使用过程中能有效避免破 损及漏气风险，其寿命可达传统升液管的十倍以上。
在提高铸件 质量的同时，显著降低了铝铸造的运行成本。
Silicon nitride riser tube is formed by isostatic pressing and sintered under gas pressure,which has excellent compactness and maintain high mechanical strength under high temperature conditions.It can effectively avoid the risk of damage and air leakage during use,which lifetime can be more than ten times that of traditional riser tubes.It not only can improve the quality of castings,but also can reduce the operating cost of aluminum casting significantly.
